Maxim Integrated MAX5382NEUK Digital Potentiometer

The MAX5382NEUK from Maxim Integrated is a compact, high-performance digital potentiometer designed for a wide range of applications requiring precise digital control over an analog signal. This device is a part of Maxim's extensive line of digital potentiometers, which are known for their reliability and versatility.

The MAX5382NEUK is a single-channel, 8-bit, non-volatile digital potentiometer that offers 256 taps, allowing for fine-grained control over resistance settings. This potentiometer operates from a 2.7V to 5.5V single-supply voltage, making it suitable for both 3V and 5V systems. Its small SOT23-8 package makes it an excellent choice for space-constrained applications.

One of the key features of the MAX5382NEUK is its SPI-compatible serial interface, which facilitates easy communication with microcontrollers and other digital systems. This interface allows users to set the wiper position without the need for complex programming, streamlining the integration process.

The device's end-to-end resistance comes in several options with the most common being 10kΩ, which is ideal for a broad range of applications, including adjustable power supplies, LCD screen adjustment, and audio signal control. Its robust design ensures stable operation over the entire temperature range of -40°C to +125°C, making it suitable for both commercial and industrial environments.

Moreover, the MAX5382NEUK features a non-volatile memory (EEPROM), which ensures that the last wiper position is stored even when the power is removed. This feature is particularly useful in applications where the potentiometer setting must be maintained between power cycles, such as in system calibration settings.

In summary, the Maxim Integrated MAX5382NEUK is a versatile, easy-to-use digital potentiometer that offers precise control over analog signals. Its compact size, SPI interface, and non-volatile memory make it an excellent choice for designers who require a reliable solution for adjusting resistance in their electronic designs.
